Local quantum dot tuning on photonic crystal chips

Quantum networks based on InAs quantum dots embedded in photonic crystal devices rely on quantum dots being in resonance with each other and with the cavities they are embedded in. The authors developed a technique based on temperature tuning to spectrally align different quantum dots located on the same chip. The technique allows for up to 1.8 nm reversible on-chip quantum dot tuning. (c) 2007 American Institute of Physics.
